Testimony on Behalf of Environmental Law & Policy Center, The Ecology Center, Union of Concerned Scientists and Vote Solar:

9 Q: What is the magnitude of total pollutants emitted and what are the emissions rates 10 from the coal plants in the DTE IRP? 11 A: The total emissions (tons) of the two coal plants included in DTE's PCA (Portfolio #2) 12 for 2023 are included in Table 1. [...] DTE should have presented the absolute impacts of each of the 20 portfolios, not only the relative difference in health impacts over the course of each of the 21 portfolios. [...] In addition to providing the cumulative impacts of Monroe Units 1 and 2 and Units 3 12 and 4 across the proposed plant lifetime, I also provide the emissions of Monroe Units 1 and 2 13 between 2031 and 2035 to evaluate the health benefits of retiring Monroe Units 1 and 2 in 2030 14 rather than 2035. [...] The largest total impacts tend to be in the more densely populated areas, while 7 the largest per-capita health impacts are near and directly downwind of the plants because 8 that is where the emissions from each plant tend to impact air quality the most. [...] While I evaluated 17 and reported all indexes and indicators in my testimony I used the metrics at or above the 18 75th percentile in the state as a starting point for my testimony.18 The results of “low- 19 income” and the “people of color” indicators are in Figure 2, and the full results of my 20 analysis are in Exhibit CEO-17.
